Every time you connect to the free Wi-Fi at a coffee shop, airport, or hotel, you’re joining a network controlled by someone else. That someone might be the business itself, or it might be an attacker running a rogue access point with a convincing name like “Starbucks_WiFi_Free.”
The Real Risks of Public Wi-Fi
On an unsecured public network, an attacker on the same Wi-Fi can potentially intercept your traffic, capture login credentials, and inject malicious content into unencrypted web pages. While HTTPS protects the content of encrypted connections, it doesn’t hide which sites you visit, and many business applications still transmit data without encryption.
The more dangerous threat is the “evil twin” attack, where an attacker sets up a Wi-Fi network with the same name as the legitimate one. Your device connects automatically because it remembers the network name, and now all your traffic flows through the attacker’s device. This attack is trivially easy to execute with free software and a $20 wireless adapter.
What This Means for Business Travelers
For employees who travel or work remotely in Central Florida, public Wi-Fi is unavoidable. Client meetings at coffee shops, conferences at the Orange County Convention Center, connecting at Orlando International Airport between flights. The answer isn’t to avoid Wi-Fi entirely, it’s to use it safely.
The single most important step is using a business VPN. A VPN encrypts all traffic between your device and your company’s network, making public Wi-Fi eavesdropping irrelevant. Even if someone intercepts your traffic, all they see is encrypted data.
Practical Steps for Your Team
Always use your company VPN before doing any work on public Wi-Fi. Make it a policy, not a suggestion. Configure devices to require VPN connection before accessing business applications.
Disable auto-connect on all work devices. This prevents your laptop or phone from automatically joining networks it has connected to before, including evil twin networks.
Use your phone’s hotspot when possible. Your cellular data connection is significantly more secure than public Wi-Fi because it’s encrypted by your carrier and much harder to intercept.
Forget public networks after using them. Go into your Wi-Fi settings and remove saved public networks so your device doesn’t reconnect automatically in the future.
These aren’t complicated steps, but they need to be part of your team’s routine. A 5-minute security briefing during onboarding can prevent a breach that costs your business thousands.
